The fixing seat is slidingly connected to the shell and located on the inner side of the shell. The first lens is fixedly connected to the fixing seat, and the second lens is fixedly connected to the shell and located on the image side of the first lens. The driving mechanism is used to make the shell and the fixing seat slide relative to each other, and the distance between the second lens and the first lens increases or decreases in the direction of the optical axis of the lens assembly.

Description

Technical Field

[0001] This application relates to the field of camera technology, and more particularly to a lens assembly, camera module, and electronic device. Background Technology

[0002] With the rapid development of key technologies such as full-screen displays and fingerprint recognition, multi-functionality has become a trend in electronic devices, especially mobile phones. This design significantly compresses the space available for camera modules. In this space-constrained environment, traditional mobile phones generally use upright camera modules to reduce their footprint in the length and width of the phone. However, traditional upright camera modules typically employ a drive motor with a reed. The deformation of the reed determines the travel distance of the camera module during focusing. Due to the structural constraints of the reed itself, its deformation is relatively small, making it difficult for the drive motor to achieve large-travel focusing, resulting in poor image quality. Summary of the Invention

[0003] This application provides a lens assembly with a long-stroke focusing capability, a camera module, and an electronic device.

[0004] In a first aspect, embodiments of this application provide a lens assembly. The lens assembly includes a housing, a mounting base, a first lens, a second lens, and a driving mechanism. The mounting base is slidably connected to the housing and is located inside the housing.

[0005] The first lens is fixedly connected to the mounting base, and the second lens is fixedly connected to the outer shell. The second lens is located on the image side of the first lens.

[0006] The drive mechanism is used to slide the housing relative to the mounting base, increasing or decreasing the distance between the second lens and the first lens along the optical axis of the lens assembly. The following description will use the Z-axis as an example for the optical axis of the lens assembly.

[0007] In this embodiment, the lens assembly is focused by increasing or decreasing the distance between the second lens and the first lens along the optical axis of the lens assembly, through the relative sliding of the driving housing and the fixed base. It is understood that, on the one hand, by increasing or decreasing the distance between the first and second lenses, the focal point position of the lens assembly is changed, which is beneficial for macro and telephoto shooting, thus greatly improving the user experience; on the other hand, compared to focusing through the deformation of a spring, the housing and fixed base in this embodiment are connected by sliding, thus avoiding the problem of limiting the focusing travel due to the structural constraints of the spring itself. The housing can slide a longer distance relative to the fixed base in this embodiment, which is more conducive to macro and telephoto shooting. For example, the maximum distance the housing can slide relative to the fixed base along the Z-axis can be 5 mm.

[0008] In one possible implementation, a drive mechanism is used to drive the housing to slide along the optical axis of the lens assembly.

[0009] Understandably, by driving the housing to slide along the optical axis of the lens assembly, the housing can move the second lens away from or closer to the first lens along the optical axis of the lens assembly. Since the second lens is located on the image side of the first lens, it is less likely for the second lens to collide with or interfere with the components on top of the first lens.

[0010] In one possible implementation, the drive mechanism includes a magnet and a coil, one of which is fixedly connected to a housing, and the other is fixedly connected to a mounting base, with the magnet and coil positioned opposite each other. In other words, when the magnet is fixedly connected to the housing, the coil is fixedly connected to the mounting base. Conversely, when the coil is fixedly connected to the housing, the magnet is fixedly connected to the mounting base.

[0011] Understandably, by using a drive mechanism with magnets and coils, the drive mechanism can be prevented from being directly connected to the housing and the mounting base, thereby avoiding the impact of bending stress on the movement accuracy of the lens assembly on the part of the drive mechanism that connects to the housing and the mounting base.

[0012] Understandably, when the drive mechanism is used to drive the housing to slide along the optical axis of the lens assembly, and the magnet is fixedly connected to the housing and the coil is fixedly connected to the mounting base, the magnet acts as the mover and the coil as the stator. This ensures that, on the one hand, the coil will not interfere with other components during movement; and on the other hand, it avoids the bending stress of the coil affecting the movement accuracy of the lens assembly.

[0013] Understandably, when the drive mechanism is used to drive the housing to slide along the optical axis of the lens assembly, and the coil is fixedly connected to the housing and the magnet is fixedly connected to the mounting base, the coil acts as the mover and the magnet as the stator. Thus, due to the relatively small weight of the coil, the driving force of the drive mechanism is relatively small.

[0014] In one possible implementation, the lens assembly includes a guide rod, a housing, and a mounting base, one of which is fixedly connected to the guide rod, and the other is slidably connected to the guide rod.

[0015] It is understandable that by setting a guide rod and fixing one of the outer shell and the fixed base to the guide rod, while the other is slidably connected to the guide rod, the guide rod can play a guiding role during the sliding of the outer shell relative to the fixed base, so that the outer shell can slide more accurately along the Z-axis direction, that is, the outer shell is not easy to deviate.

[0016] In one possible implementation, the outer casing has a first groove and a second groove spaced apart, and the mounting base has a third groove and a fourth groove spaced apart. The guide rod includes a first guide rod and a second guide rod. The first guide rod is slidably connected to the groove wall of the first groove and fixedly connected to the groove wall of the third groove. The second guide rod is slidably connected to the groove wall of the second groove and fixedly connected to the groove wall of the fourth groove.

[0017] It can be understood that by setting the cooperation of the first guide rod and the first slide groove (that is, the first groove and the third groove), and the cooperation of the second guide rod and the second slide groove (the second groove and the fourth groove), the outer shell can play a guiding role in the process of sliding relative to the fixed seat, so that the outer shell can slide more accurately along the Z-axis direction, that is, the outer shell is not easy to deviate.

[0018] Furthermore, by dividing the first slide groove into a first recess and a third recess, the assembly difficulty of the first guide rod and the first slide groove is reduced. For example, the first guide rod can be placed in the third recess first, then the first guide rod can be glued to the groove wall of the third recess using adhesive, and finally the first recess and the first guide rod can be assembled.

[0019] In one possible implementation, the wall of the first groove is V-shaped, and the wall of the second groove is arc-shaped, []-shaped, or U-shaped; or the wall of the first groove is arc-shaped, []-shaped, or U-shaped, and the second groove is V-shaped.

[0020] Understandably, in one possible implementation, by setting the groove wall of the first groove to a "V" shape, the two groove walls of the first groove can maintain contact with the first guide rod, making it easier for the two groove walls of the first groove to clamp the first guide rod. This results in a more stable connection between the housing, the first guide rod, and the mounting base. Furthermore, by setting the second groove of the housing to a "[" shape, a circle, or a U-shape, a certain margin of error can be allowed between the groove wall of the second groove and the second guide rod, ensuring that the second guide rod and the second groove are not difficult to assemble due to positional errors.

[0021] In one possible implementation, the lens assembly includes a first magnetic clasp and a second magnetic clasp. The first magnetic clasp is fixedly connected to the housing, and the second magnetic clasp is fixedly connected to the mounting base. The guide rod remains in contact with the housing and the mounting base under the attraction of the first and second magnetic clasps.

[0022] Understandably, by fixing the first magnetic component to the outer shell and the second magnetic component to the mounting base, the attraction force generated by the first and second magnetic components in the Y-axis direction is used to keep the outer shell, the first guide rod, the second guide rod, and the mounting base in close contact. This prevents the mounting base from easily wobbling relative to the outer shell.

[0023] In one possible implementation, the outer casing has a first fixing groove, and the fixing base has a second fixing groove. The first magnetic member is located in the first fixing groove, and the second magnetic member is located in the second fixing groove.

[0024] It is understandable that by setting the first magnetic component in the first fixing groove, the connection area between the first magnetic component and the housing can be increased, thereby improving the connection between the first magnetic component and the housing. On the other hand, it is beneficial to the miniaturization and lightweight design of the lens assembly.

[0025] In addition, by setting the second magnetic component in the second fixing groove, the connection area between the second magnetic component and the housing can be increased, thereby improving the connection between the second magnetic component and the housing. On the other hand, it is also conducive to further miniaturization and lightweight design of the lens assembly.

[0026] In one possible implementation, the guide rod includes a first guide rod and a second guide rod spaced apart, with the first and second guide rods located on the same side of the mounting base. A second magnetic attractor is located between the first and second guide rods, or on the side of the first guide rod away from the second guide rod, or on the side of the second guide rod away from the first guide rod.

[0027] Understandably, the arrangement of the second magnetic component, the first guide rod, and the second guide rod is more compact, which increases the force between the outer shell and the fixing base, and makes the connection between the outer shell, the first guide rod, the second guide rod, and the fixing base more stable.

[0028] In one possible implementation, the lens assembly includes a tunnel magnetoresistive sensor and a magnetic grating, one of which is fixedly connected to the housing and the other is fixed to the mounting base. The tunnel magnetoresistive sensor is used to detect the magnetic field strength of the magnetic grating at different locations.

[0029] Understandably, when the housing moves relative to the fixed base along the Z-axis, the housing can drive the magnetic grating to move relative to the fixed base along the Z-axis. The tunnel magnetoresistive sensor can detect the magnetic field strength at the location of the magnetic grating. Thus, when the tunnel magnetoresistive sensor detects the magnetic field strength of the magnetic grating, the displacement of the housing can be determined based on the magnetic field strength. It is understood that through the cooperation of the tunnel magnetoresistive sensor and the magnetic grating, the displacement of the housing relative to the fixed base along the Z-axis can be accurately controlled, thereby achieving a closed-loop design for the lens assembly.

[0030] Furthermore, compared to the solution using a Hall sensor and a magnet, this embodiment uses a tunnel magnetoresistive sensor in combination with a magnetic grating, which can accurately measure the outer shell with large displacement.

[0031] In one possible implementation, the lens assembly includes a first buffer member fixedly connected to the bottom surface of the mounting base. Thus, when the housing moves the second lens along the positive Z-axis, the first buffer member can cushion the impact force between the bottom plate of the housing and the mounting base, preventing damage to either the bottom plate or the mounting base.

[0032] In one possible implementation, the first lens includes a lens cover, a first lens barrel, and a number of first lens elements. At least one first lens element is fixed between the lens cover and the first lens barrel. The remaining first lens elements are fixedly connected to the first lens barrel.

[0033] In one possible implementation, the second lens includes a second lens barrel and a second lens element. The second lens element is fixedly connected to the second lens barrel.

[0034] In one possible implementation, a drive mechanism is used to drive the mounting base to slide along the optical axis of the lens assembly.

[0035] Secondly, embodiments of this application provide a camera module. The camera module includes a module circuit board, a photosensitive chip, and a lens assembly as described above. The photosensitive chip is fixedly connected to the module circuit board and electrically connected to the module circuit board. The housing of the lens assembly is connected to the module circuit board, and a second lens is located on the object side of the photosensitive chip.

[0036] Understandably, on the one hand, by increasing or decreasing the distance between the first and second lenses, the focal point position of the lens assembly can be changed, which is beneficial for achieving macro and telephoto shooting by the camera module, thus greatly improving the user experience. On the other hand, compared to the solution of achieving focus through the deformation of a spring, the housing and the mounting base in this embodiment are connected by sliding. This avoids the problem of limiting the focusing travel due to the structural constraints of the spring itself. The housing in this embodiment can slide a longer distance relative to the mounting base, which is more conducive to achieving macro and telephoto shooting by the camera module. For example, the maximum distance that the housing can slide relative to the mounting base along the Z-axis can be 5 mm.

[0037] In one possible implementation, the camera module includes a base, with the base fixedly connected to the module circuit board, and the lens assembly housing slidably connected to the base. The lens assembly includes a second buffer, which is fixedly connected to the bottom of the housing.

[0038] In this way, when the lens assembly housing slides relative to the base, the second buffer can cushion the impact force between the bottom plate of the housing and the base, so as to avoid damage to the bottom plate or base of the housing.

[0039] Thirdly, embodiments of this application provide an electronic device. The electronic device includes a housing and a camera module. The module circuit board includes a module circuit board, a photosensitive chip, and a lens assembly. The module circuit board is connected to the housing, and the photosensitive chip is fixedly connected to and electrically connected to the module circuit board.

[0040] The lens assembly includes a housing, a mounting base, a first lens, a second lens, and a drive mechanism. The housing is connected to the module circuit board. The mounting base is slidably connected to the housing and is located inside the housing. The first lens is fixedly connected to the mounting base, and the second lens is fixedly connected to the housing. The second lens is located on the image side of the first lens and on the object side of the image sensor.

[0041] The drive mechanism is used to slide the housing relative to the mounting base, thereby increasing or decreasing the distance between the second lens and the first lens in the optical axis direction of the lens assembly.

[0042] Understandably, on the one hand, by increasing or decreasing the distance between the first and second lenses, the focal point position of the lens assembly can be changed, thereby facilitating macro and telephoto shooting with the electronic device and significantly improving the user experience. On the other hand, compared to solutions that achieve focusing through the deformation of a spring, the housing and the mounting base in this embodiment are connected by sliding. This avoids the problem of limiting the focusing travel due to the structural constraints of the spring itself. The housing in this embodiment can slide a longer distance relative to the mounting base, which is more conducive to macro and telephoto shooting with the electronic device. For example, the maximum distance the housing can slide relative to the mounting base along the Z-axis can be 5 mm.

[0043] In one possible implementation, the housing includes a back cover. The electronic device includes a camera trim and a drive mechanism, the camera trim being slidably connected to the back cover; a first lens is fixedly connected to the camera trim. The drive mechanism is used to drive the camera trim to move the lens assembly along the optical axis of the camera module.

[0044] It is understandable that by driving the camera trim piece through a drive device, the lens assembly is moved along the optical axis of the camera module, thereby significantly increasing the size of the bottom space of the lens assembly. In this way, when the drive mechanism is used to drive the housing to slide along the optical axis of the lens assembly, the bottom space of the lens assembly can accommodate the movement of the lens assembly to a greater extent.

[0045] In one possible implementation, the housing includes a back cover; the electronic device includes a camera trim piece fixedly connected to the back cover; and a first lens is fixedly connected to the camera trim piece.

[0046] In one possible implementation, a drive mechanism is used to drive the housing to slide along the optical axis of the lens assembly.

[0047] Understandably, by driving the housing to slide along the optical axis of the lens assembly, the housing can move the second lens away from or closer to the first lens along the optical axis of the lens assembly. Since the second lens is located on the image side of the first lens, it is less likely for the second lens to collide with or interfere with the rear cover.

[0048] In one possible implementation, the drive mechanism includes a magnet and a coil, one of which is fixedly connected to the housing and the other is fixedly connected to the mounting base, with the magnet and coil arranged opposite each other.

[0049] Understandably, by using a drive mechanism with magnets and coils, the drive mechanism can be prevented from being directly connected to the housing and the mounting base, thereby avoiding the impact of bending stress on the movement accuracy of the lens assembly on the part of the drive mechanism that connects to the housing and the mounting base.

[0050] Understandably, when the drive mechanism is used to drive the housing to slide along the optical axis of the lens assembly, and the magnet is fixedly connected to the housing and the coil is fixedly connected to the mounting base, the magnet acts as the mover and the coil as the stator. This ensures that, on the one hand, the coil will not interfere with other components during movement; and on the other hand, it avoids the bending stress of the coil affecting the movement accuracy of the lens assembly.

[0051] Understandably, when the drive mechanism is used to drive the housing to slide along the optical axis of the lens assembly, and the coil is fixedly connected to the housing and the magnet is fixedly connected to the mounting base, the coil acts as the mover and the magnet as the stator. Thus, due to the relatively small weight of the coil, the driving force of the drive mechanism is relatively small.

[0052] In one possible implementation, the lens assembly includes a guide rod, a housing, and a mounting base, one of which is fixedly connected to the guide rod, and the other is slidably connected to the guide rod.

[0053] It is understandable that by setting a guide rod and fixing one of the outer shell and the fixed base to the guide rod, while the other is slidably connected to the guide rod, the guide rod can play a guiding role during the sliding of the outer shell relative to the fixed base, so that the outer shell can slide more accurately along the Z-axis direction, that is, the outer shell is not easy to deviate.

[0054] In one possible implementation, the outer casing has a first groove and a second groove spaced apart, and the mounting base has a third groove and a fourth groove spaced apart. The guide rod includes a first guide rod and a second guide rod. The first guide rod is slidably connected to the groove wall of the first groove and fixedly connected to the groove wall of the third groove. The second guide rod is slidably connected to the groove wall of the second groove and fixedly connected to the groove wall of the fourth groove.

[0055] It can be understood that by setting the cooperation of the first guide rod and the first slide groove (that is, the first groove and the third groove), and the cooperation of the second guide rod and the second slide groove (the second groove and the fourth groove), the outer shell can play a guiding role in the process of sliding relative to the fixed seat, so that the outer shell can slide more accurately along the Z-axis direction, that is, the outer shell is not easy to deviate.

[0056] Furthermore, by dividing the first slide groove into a first recess and a third recess, the assembly difficulty of the first guide rod and the first slide groove is reduced. For example, the first guide rod can be placed in the third recess first, then the first guide rod can be glued to the groove wall of the third recess using adhesive, and finally the first recess and the first guide rod can be assembled.

[0057] In one possible implementation, the wall of the first groove is V-shaped, and the wall of the second groove is arc-shaped, []-shaped, or U-shaped; or the wall of the first groove is arc-shaped, []-shaped, or U-shaped, and the second groove is V-shaped.

[0058] Understandably, in one possible implementation, by setting the groove wall of the first groove to a "V" shape, the two groove walls of the first groove can maintain contact with the first guide rod, making it easier for the two groove walls of the first groove to clamp the first guide rod. This results in a more stable connection between the housing, the first guide rod, and the mounting base. Furthermore, by setting the second groove of the housing to a "[" shape, a circle, or a U-shape, a certain margin of error can be allowed between the groove wall of the second groove and the second guide rod, ensuring that the second guide rod and the second groove are not difficult to assemble due to positional errors.

[0059] In one possible implementation, the lens assembly includes a first magnetic clasp and a second magnetic clasp. The first magnetic clasp is fixedly connected to the housing, and the second magnetic clasp is fixedly connected to the mounting base. The guide rod remains in contact with the housing and the mounting base under the attraction of the first and second magnetic clasps.

[0060] Understandably, by fixing the first magnetic component to the outer shell and the second magnetic component to the mounting base, the attraction force generated by the first and second magnetic components in the Y-axis direction is used to keep the outer shell, the first guide rod, the second guide rod, and the mounting base in close contact. This prevents the mounting base from easily wobbling relative to the outer shell.

[0061] In one possible implementation, the outer casing has a first fixing groove, and the fixing base has a second fixing groove. The first magnetic member is located in the first fixing groove, and the second magnetic member is located in the second fixing groove.

[0062] It is understandable that by setting the first magnetic component in the first fixing groove, the connection area between the first magnetic component and the housing can be increased, thereby improving the connection between the first magnetic component and the housing. On the other hand, it is beneficial to the miniaturization and lightweight design of the lens assembly.

[0063] In addition, by setting the second magnetic component in the second fixing groove, the connection area between the second magnetic component and the housing can be increased, thereby improving the connection between the second magnetic component and the housing. On the other hand, it is also conducive to further miniaturization and lightweight design of the lens assembly.

[0064] In one possible implementation, the guide rod includes a first guide rod and a second guide rod spaced apart, with the first guide rod and the second guide rod located on the same side of the fixed base;

[0065] The second magnetic attractor is located between the first guide rod and the second guide rod, or on the side of the first guide rod away from the second guide rod, or on the side of the second guide rod away from the first guide rod.

[0066] Understandably, the arrangement of the second magnetic component, the first guide rod, and the second guide rod is more compact, which increases the force between the outer shell and the fixing base, and makes the connection between the outer shell, the first guide rod, the second guide rod, and the fixing base more stable.

[0067] In one possible implementation, the lens assembly includes a tunnel magnetoresistive sensor and a magnetic grating, one of which is fixedly connected to the housing and the other is fixed to the mounting base. The tunnel magnetoresistive sensor is used to detect the magnetic field strength of the magnetic grating at different locations.

[0068] Understandably, when the housing moves relative to the fixed base along the Z-axis, the housing can drive the magnetic grating to move relative to the fixed base along the Z-axis. The tunnel magnetoresistive sensor can detect the magnetic field strength at the location of the magnetic grating. Thus, when the tunnel magnetoresistive sensor detects the magnetic field strength of the magnetic grating, the displacement of the housing can be determined based on the magnetic field strength. It is understood that through the cooperation of the tunnel magnetoresistive sensor and the magnetic grating, the displacement of the housing relative to the fixed base along the Z-axis can be accurately controlled, thereby achieving a closed-loop design for the lens assembly.

[0069] Furthermore, compared to the solution using a Hall sensor and a magnet, this embodiment uses a tunnel magnetoresistive sensor in combination with a magnetic grating, which can accurately measure the outer shell with large displacement.

[0070] In one possible implementation, the first lens includes a lens cover, a first lens barrel, and a number of first lens elements. At least one first lens element is fixed between the lens cover and the first lens barrel. The remaining first lens elements are fixedly connected to the first lens barrel.

[0071] In one possible implementation, the second lens includes a second lens barrel and a second lens element. The second lens element is fixedly connected to the second lens barrel.

[0072] In one possible implementation, a drive mechanism is used to drive the mounting base to slide along the optical axis of the lens assembly.

[0073] In one possible implementation, the lens assembly includes a first buffer member fixedly connected to the bottom surface of the mounting base. Thus, when the housing moves the second lens along the positive Z-axis, the first buffer member can cushion the impact force between the bottom plate of the housing and the mounting base, preventing damage to either the bottom plate or the mounting base.

The screen 300, the frame 201, and the back cover 202 can together enclose the interior of the electronic device 1. The interior of the electronic device 1 can be used to house components of the electronic device 1, such as a battery, receiver, or microphone. The screen 300 can be used to display images, etc. The screen 300 can be a flat screen or a curved screen.

[0111] In this embodiment, the rear cover 202 is provided with mounting holes 203. The mounting holes 203 penetrate two opposite surfaces of the rear cover 202. The mounting holes 203 connect the interior of the electronic device 1 to the exterior of the electronic device 1.

[0112] In one embodiment, the electronic device 1 further includes a camera trim 80, a drive unit 90, and a seal 91.

[0113] The camera trim 80 is movably connected to the back cover 202. At least a portion of the camera trim 80 may be located within the mounting hole 203. The camera trim 80 can separate the interior of the electronic device 1 from the exterior of the electronic device 1.

[0114] The drive unit 90 may be located inside the electronic device 1. The drive unit 90 is connected to the camera decoration 80. The drive unit 90 can be used to drive the camera decoration 80 to move along the Z-axis direction. It should be understood that the specific structure of the drive unit 90 is not limited; for example, the drive unit 90 may be a motor or a lifting mechanism.

[0115] The seal 91 connects the camera trim 80 and the back cover 202. The seal 91 seals the gap between the camera trim 80 and the mounting hole 203. The seal 91 can be made of a flexible material (such as soft rubber, etc.). Specifically, when the camera trim 80 moves relative to the back cover 202 along the Z-axis, the seal 91 can deform to fit the gap between the camera trim 80 and the mounting hole 203.

[0116] In other embodiments, the camera trim 80 may also be fixedly connected to the back cover 202. In this case, the electronic device 1 may not include the drive unit 90.

[0117] In other embodiments, the electronic device 1 may not include the seal 91. In this case, some structure of the camera trim 80 itself is used to seal the gap between the camera trim 80 and the mounting hole 203.

[0118] In this embodiment, the camera module 100 is located inside the electronic device 1. The camera module 100 is a vertical camera module, that is, the optical axis of the camera module 100 is in the Z-axis direction. The camera module 100 can be a rear camera module or a front camera module, etc. Figure 1 and Figure 2 This indicates that camera module 100 is a rear-facing camera module.

[0119] In other embodiments, the position of the camera module 100 is not specifically limited.

[0120] In this embodiment, the camera module 100 is fixedly connected to the camera decorative piece 80. When the camera decorative piece 80 moves relative to the back cover 202 along the Z-axis, the camera decorative piece 80 can drive a portion of the camera module 100 to move along the Z-axis.

[0121] In other embodiments, when the camera trim 80 is fixedly connected to the back cover 202, the camera module 100 is fixed relative to the back cover 202.

[0122] In one embodiment, at least a portion of the camera trim 80 may be made of a transparent material (e.g., glass or transparent plastic). This allows ambient light from outside the electronic device 1 to pass through the camera trim 80 and enter the interior of the electronic device 1. The camera module 100 then captures the ambient light entering the interior of the electronic device 1.

[0123] It is understood that the camera trim 80, the drive unit 90, and the seal 91 can be part of the camera module 100. In other words, the camera trim 80, the drive unit 90, and the seal 91 can be integrated with the camera module 100 as a single product. In other embodiments, the camera trim 80, the drive unit 90, the seal 91, and the camera module 100 can each be a separate product.

[0124] Please see Figure 2 and Figure 3 , Figure 3 yes Figure 2The diagram shows a partial cross-sectional view of the electronic device 1 in its pop-up state. In this embodiment, the electronic device 1 has three states: non-pop-up state (also called non-working state or stopped state), pop-up state, and focusing state. Figure 2 This indicates that electronic device 1 is in the non-ejected state. Figure 3 This indicates that electronic device 1 is in the pop-up state. The focusing state of electronic device 1 will be described in detail below with reference to specific accompanying images. It will not be elaborated further here. It can be understood that the non-pop-up state of electronic device 1 can be the state where electronic device 1 is not taking pictures, or the state before initiating shooting. The pop-up state of electronic device 1 can be the state where electronic device 1 is preparing to take pictures. The focusing state of electronic device 1 can be the state where electronic device 1 is taking pictures.

[0125] In this embodiment, the electronic device 1 has three states, and the camera module 100 also has three corresponding states. In other words, the camera module 100 has a non-pop-up state, a pop-up state, and a focusing state. Specific details will not be elaborated here.

[0126] In other embodiments, when the camera trim 80 is fixedly connected to the back cover 202, the electronic device 1 has two states: a non-pop-up state (also known as a non-working state or a stopped state) and a focusing state. The camera module 100 also has two corresponding states. In other words, the camera module 100 has a non-pop-up state and a focusing state.

[0127] Please refer to it again. Figure 2 and Figure 3 When the electronic device 1 is in a non-pop-up state (i.e., the camera module 100 is in a non-pop-up state), the height of the camera module 100 in the Z-axis direction is a first height H1. When the electronic device 1 is in a pop-up state (i.e., the camera module 100 is in a pop-up state), the height of the camera module 100 in the Z-axis direction is a second height H2. The second height H2 is greater than the first height H1. It can be understood that this embodiment, by adding an extra state of the camera module 100 (i.e., the pop-up state of the camera module 100), enables the camera module 100 to have a larger focusing space in the Z-axis direction during operation. This will be described in detail below with reference to the relevant accompanying drawings.

[0128] Understandably, when the electronic device 1 transitions from a non-pop-up state to a pop-up state, the drive device 90 drives the camera decorative piece 80 to move relative to the back cover 202 along the positive Z-axis. At least a portion of the camera decorative piece 80 can move to the outside of the mounting hole 203, and the camera decorative piece 80 can drive a portion of the camera module 100 to move to the outside of the mounting hole 203. When the electronic device 1 transitions from a pop-up state to a non-pop-up state, the drive device 90 drives the camera decorative piece 80 to move relative to the back cover 202 along the negative Z-axis. At least a portion of the camera decorative piece 80 can move into the mounting hole 203, and the camera decorative piece 80 can drive a portion of the camera module 100 to move to the inside of the mounting hole 203.

[0129] Please see Figure 4 , Figure 4 yes Figure 2 The diagram shows a partially exploded view of the camera module 100. The camera module 100 includes a module circuit board 10, a photosensitive chip 20, a module bracket 30, a filter 40, a base 50, and a lens assembly 60a. The photosensitive chip 20 is also called an image sensor or a photosensitive element. The photosensitive chip 20 is used to collect ambient light and convert the image information carried by the ambient light into electrical signals. It should be noted that the optical axis of the lens assembly 60a is the same as the optical axis of the camera module 100.

[0130] Please see Figure 4 and combined Figure 3 As shown, in one embodiment, the photosensitive chip 20 is fixed to and electrically connected to the module circuit board 10. In this case, the photosensitive chip 20 and the module circuit board 10 can transmit signals to each other. A module bracket 30 is fixedly connected to the module circuit board 10. The module bracket 30 and the photosensitive chip 20 are located on the same side of the module circuit board 10. The module bracket 30 has a light-transmitting hole 31. A filter 40 is fixedly connected to the module bracket 30 and located within the light-transmitting hole 31. The filter 40 is also disposed opposite to the photosensitive chip 20. The filter 40 can be used to filter infrared light or blue light from ambient light, thereby ensuring that the photosensitive chip 20 has better imaging quality.

[0131] In one embodiment, the base 50 is located on the side of the module bracket 30 away from the module circuit board 10. The base 50 is fixed to the module bracket 30. The base 50 encloses an active space 32. The base 50 is provided with a light-transmitting hole 51. The light-transmitting hole 51 of the base 50 connects the active space 32 with the light-transmitting hole 31 of the module bracket 30. The light-transmitting hole 51 of the base 50 and the light-transmitting hole 31 of the module bracket 30 are arranged opposite to each other.

[0132] In one embodiment, the lens assembly 60a is movably connected to the base 50. At least a portion of the lens assembly 60a is located within the movable space 32. Exemplarily, the lens assembly 60a can be slidably connected to the base 50. For example, sliding of the lens assembly 60a relative to the base 50 can be achieved by providing a mating mechanism of guide rails and grooves between the lens assembly 60a and the base 50.

[0133] Please refer to it again. Figure 2 When the electronic device 1 is in the non-ejected state, most of the lens assembly 60a is located within the active space 32. Please refer again. Figure 3 When the electronic device 1 is in the pop-up state, most of the lens assembly 60a is located outside the active space 32. At this time, the space enclosed by the lens assembly 60a, the base 50, and the module bracket 30 (i.e., part of the active space 32) can be used as the focusing space of the camera module 100.

[0134] Please refer to it again. Figure 2 and Figure 3 When the electronic device 1 transitions from a non-pop-up state to a pop-up state, the drive device 90 drives the camera trim 80 to move relative to the back cover 202 along the positive Z-axis. The camera trim 80 can then drive the lens assembly 60a to move along the positive Z-axis, with a portion of the lens assembly 60a moving from inside the active space 32 to outside the active space 32. At this time, the distance between the lens assembly 60a and the photosensitive chip 20 increases. When the electronic device 1 transitions from a pop-up state to a non-pop-up state, the drive device 90 drives the camera trim 80 to move relative to the back cover 202 along the negative Z-axis. The camera trim 80 can then drive the lens assembly 60a to move along the negative Z-axis, with a portion of the lens assembly 60a moving from outside the active space 32 to inside the active space 32. At this time, the distance between the lens assembly 60a and the photosensitive chip 20 decreases.

[0135] Please see Figure 5 and combined Figure 4 As shown, Figure 5 yes Figure 4 The diagram shows a partially exploded view of the lens assembly 60a. The lens assembly 60a includes a lens motor 60, a first lens 71, and a second lens 72. Both the first lens 71 and the second lens 72 are mounted on the lens motor 60. The lens motor 60 drives the second lens 72 to move relative to the first lens 71 along the Z-axis, thereby achieving autofocus (AF) of the lens assembly 60a. The specific connection relationships between the first lens 71, the second lens 72, and the lens motor 60 will be described in detail below with reference to the accompanying drawings.

[0136] It is understood that the lens motor 60 can be a voice coil motor, an SMA (shape memory alloy) motor, or a motor with other structures. This application does not specifically limit its application. It should be understood that an SMA motor can be a motor that uses the contraction of SMA wires to generate driving force. The material of the SMA wires can be a nickel-titanium alloy. Furthermore, SMA is a general term for a class of metals with shape memory effect. In this embodiment, the lens motor 60 is described using a voice coil motor as an example.

[0137] Please see Figure 6 , Figure 6 yes Figure 5 The diagram shows a partially exploded view of the lens motor 60. The lens motor 60 includes a housing 61, a mounting base 62, a guide rod 63, a coil 64, a magnet 65, a first magnetic attractor 66, a second magnetic attractor 67, and a motor circuit board 68. In this embodiment, the number of guide rods 63, coils 64, magnets 65, first magnetic attractors 66, and second magnetic attractors 67 are all two. Specifically, the guide rod 63 includes a first guide rod 63a and a second guide rod 63b. The coil 64 includes a first coil 64a and a second coil 64b. The magnet 65 includes a first magnet 65a and a second magnet 65b. The first magnetic attractors 66 are designated with the same reference numerals. The two second magnetic attractors 67 are designated with the same reference numerals. In other embodiments, the number of guide rods 63, coils 64, magnets 65, first magnetic attractors 66, and second magnetic attractors 67 is not specifically limited.

[0138] In this embodiment, coil 64 and magnet 65 can constitute the drive mechanism 77 of lens motor 60. Thus, the structure of the drive mechanism 77 in this embodiment is relatively simple. In other embodiments, the drive mechanism 77 of lens motor 60 can also employ other mechanisms, such as a lifting mechanism.

[0139] Please see Figure 7 , Figure 7 yes Figure 6 The diagram shows an exploded view of the outer casing 61. The outer casing 61 includes a base plate 611, a frame 612, a first plate 613, and a second plate 614.

[0140] For example, the base plate 611 is provided with a light-transmitting hole 6111. The frame 612 is provided with a heat dissipation hole 6127.

The third side plate 6124 and the fourth side plate 6125 are connected between the first side plate 6122 and the second side plate 6123. The top plate 6121 is connected between the first side plate 6122 and the second side plate 6123, and between the third side plate 6124 and the fourth side plate 6125. The top plate 6121 is provided with a through hole 6126. Heat dissipation holes 6127 may be distributed between the first side plate 6122, the second side plate 6123, the third side plate 6124, and the fourth side plate 6125. In other embodiments, the shape of the frame 612 is not limited to... Figure 7 The shape shown is a cuboid, such as a cylinder.

[0142] Please see Figure 8 and combined Figure 7 As shown, Figure 8 yes Figure 7 The diagram shows the structure of the first plate 613 and the second plate 614 from another angle. The first plate 613 includes a top surface 6131 and a bottom surface 6132 facing away from each other, as well as a first plate surface 6133 and a second plate surface 6134 facing away from each other. The first plate surface 6133 and the second plate surface 6134 are connected between the top surface 6131 and the bottom surface 6132.

[0143] In one embodiment, the first plate 613 is provided with a first groove 6135 and a second groove 6136 spaced apart. The opening of the first groove 6135 is located on the top surface 6131, the bottom surface 6132 and the first plate surface 6133. The opening of the second groove 6136 is located on the top surface 6131, the bottom surface 6132 and the first plate surface 6133.

[0144] For example, the wall of the first groove 6135 may be V-shaped. The wall of the second groove 6136 may be [-] shaped, circular, or U-shaped, etc. In other embodiments, the wall of the second groove 6136 may be V-shaped. The wall of the first groove 6135 may be [-] shaped, circular, or U-shaped, etc.

[0145] In one embodiment, the first plate 613 is provided with a third fixing groove 6138. The opening of the third fixing groove 6138 may be located on the top surface 6131, the bottom surface 6132, and the first plate surface 6133. In other embodiments, the opening of the third fixing groove 6138 may be located only on the first plate surface 6133.

[0146] Please see Figure 7 and combined Figure 8As shown, the first plate 613 is provided with a first fixing groove 6137. The opening of the first fixing groove 6137 can be located on the top surface 6131, the bottom surface 6132, and the second plate surface 6134. In other embodiments, the opening of the first fixing groove 6137 can also be located only on the second plate surface 6134. The number of first fixing grooves is not limited to... Figure 7 and Figure 8 The two are shown. The number of the first fixing slots can be the same as the number of the first magnetic 66 (see [reference]). Figure 6 The number is the same.

[0147] Please refer to it again. Figure 7 and combined Figure 8 As shown, in one embodiment, the second plate 614 includes a first plate surface 6141 and a second plate surface 6142 disposed opposite to each other. The second plate 614 has a protrusion 6143. The protrusion 6143 is a structure in which the first plate surface 6141 of the second plate 614 protrudes in a direction away from the second plate surface 6142. At least a portion (i.e., part or all) of the surface of the protrusion 6143 facing away from the second plate surface 6142 is an arcuate surface.

[0148] Please see Figure 9 , Figure 9 yes Figure 6 The diagram shows a cross-sectional view of the outer casing 61 at line BB. The frame 612 is fixedly connected to the periphery of the base plate 611 and is arranged around the light-transmitting hole 6111 of the base plate 611. The through hole 6126 of the top plate 6121 is arranged opposite to the light-transmitting hole 6111 of the base plate 611.

[0149] In this embodiment, the frame 612 can be fixedly connected to the base plate 611 by welding or bonding. In other embodiments, the frame 612 and the base plate 611 can also be an integrally formed structure, that is, the frame 612 and the base plate 611 are a whole.

[0150] Please refer to it again. Figure 9 The first plate 613 is fixedly connected to the frame 612. Exemplarily, the second surface 6134 of the first plate 613 can be fixedly connected to the first side plate 6122 of the frame 612 by welding or bonding. In other embodiments, the first plate 613 can also be integrally formed with the frame 612, that is, the first plate 613 and the frame 612 form a single unit.

[0151] For example, the bottom surface 6132 of the first plate 613 can be fixedly connected to the base plate 611 by welding or bonding. In this way, the connection between the first plate 613, the frame 612, and the base plate 611 is more secure. In other embodiments, the first plate 613 can also be integrally formed with the base plate 611.

[0152] Please see Figure 10 , Figure 10 yes Figure 9 The diagram shows a cross-sectional view of the outer casing 61 from another angle. The second plate 614 is fixedly connected to the frame 612. Exemplarily, the second surface 6142 of the second plate 614 can be fixedly connected to the second side plate 6123 of the frame 612 by welding or bonding. In other embodiments, the second plate 614 may also be integrally formed with the frame 612.

[0153] For example, the second plate 614 can be fixedly connected to the base plate 611 by welding or bonding. This makes the connection between the second plate 614, the frame 612, and the base plate 611 more robust. In other embodiments, the second plate 614 can also be integrally formed with the base plate 611.

[0154] Please refer to it again. Figure 9 and Figure 10 The base plate 611, frame 612, first plate 613, and second plate 614 enclose a receiving space 615, which is the internal space of the outer shell 61. The receiving space 615 connects the through hole 6126 of the top plate 6121 with the light-transmitting hole 6111 of the base plate 611.

[0155] Please see Figure 11 , Figure 11 yes Figure 6 The diagram shows the structure of the fixing base 62 at different angles. In one embodiment, the fixing base 62 includes a top surface 621 and a bottom surface 622 facing away from each other, a first side surface 623 and a second side surface 624 facing away from each other, and a third side surface 625 and a fourth side surface 626 facing away from each other. The first side surface 623 and the second side surface 624 are connected between the top surface 621 and the bottom surface 622. The third side surface 625 and the fourth side surface 626 are connected between the top surface 621 and the bottom surface 622, and also connected between the first side surface 623 and the second side surface 624.

[0156] For example, the mounting base 62 is provided with a mounting hole 6271. The opening of the mounting hole 6271 is located on the top surface 621 and the bottom surface 622.

[0157] For example, the fixing base 62 is provided with a third groove 6272 and a fourth groove 6273 spaced apart. The opening of the third groove 6272 may be located on the top surface 621, the bottom surface 622, and the first side surface 623. The opening of the fourth groove 6273 may be located on the top surface 621, the bottom surface 622, and the first side surface 623. For example, the groove walls of the third groove 6272 and the fourth groove 6273 may be arc-shaped, "["-shaped, or U-shaped, etc.

[0158] In one embodiment, the mounting base 62 is provided with a second mounting groove 6274. The opening of the second mounting groove 6274 may be located on the top surface 621, the bottom surface 622, and the first side surface 623. In other embodiments, the opening of the second mounting groove 6274 may be located only on the first side surface 623.

[0159] For example, there are two second fixing slots 6274. The two second fixing slots 6274 may be located between the third groove 6272 and the fourth groove 6273. In other embodiments, the number and position of the second fixing slots 6274 are not specifically limited.

[0160] By way of example, the mounting base 62 is provided with a clearance groove 6275. The opening of the clearance groove 6275 is located on the second side 624. At least a portion of the bottom wall of the clearance groove 6275 is arcuate.

[0161] Please see Figure 12 , Figure 12 yes Figure 5 The image shows a partial cross-sectional view of the lens motor 60 at the CC line. A mounting base 62 is slidably connected to a housing 61. At least a portion of the mounting base 62 may be located within the receiving space 615 of the housing 61, that is, at least a portion of the mounting base 62 may be located inside the housing 61. Exemplarily, the housing 61 may slide relative to the mounting base 62 along the Z-axis.

[0162] In this embodiment, the first groove 6135 of the first plate 613 ( Figure 8 The diagram illustrates the first groove 6135 and the third groove 6272 of the fixing seat 62 at different angles. Figure 11 The diagram illustrates the fourth groove 6273 at different angles, which surrounds the first groove 616. The second groove 6136 of the first plate 613... Figure 8 The diagram illustrates the second groove 6136 and the fourth groove 6273 of the fixing seat 62 at different angles. Figure 11 The diagram illustrates how the fourth groove 6273 surrounds the second slide groove 617 at different angles.

[0163] Please refer to it again. Figure 12 The first fixing groove 6137 of the first plate 613 ( Figure 7 The diagram illustrates the first fixing groove 6137 and the second fixing groove 6274 of the fixing seat 62 at different angles. Figure 11 The diagram illustrates the relative arrangement of the second fixing slot 6274 at different angles. When there are multiple first fixing slots 6137 and multiple second fixing slots 6274, the multiple first fixing slots 6137 and multiple second fixing slots 6274 are arranged relative to each other in a one-to-one correspondence.

[0164] Please see Figure 13 , Figure 13 yes Figure 12 The image shows a cross-sectional view of the lens motor 60 at another angle. At least a portion of the protrusion 6143 on the second plate 614 is located within the clearance groove 6275 of the mounting base 62. The arcuate surface of the protrusion 6143 can mate with the arcuate surface of the clearance groove 6275.

[0165] Please see Figure 14 , Figure 14 yes Figure 5 The image shows a partial cross-sectional view of the lens motor 60 at the DD line. The length extension direction of the first guide rod 63a can be the Z-axis direction. The first guide rod 63a is disposed within the first sliding groove 616. The first guide rod 63a can be fixed within the third groove 6272 of the fixing base 62. The first guide rod 63a can slide relative to the first groove 6135. It is understood that the first guide rod 63a can also be fixed to the fixing base 62 by means of bonding or welding. In other embodiments, the first guide rod 63a can be integrally formed with the fixing base 62.

[0166] In other embodiments, the first groove 6135 may also be provided in the fixing base 62. The third groove 6272 may also be provided in the first plate 613. In this case, the first guide rod 63a may also be fixed in the third groove 6272 of the first plate 613. The first guide rod 63a slides relative to the first groove 6135 of the fixing base 62.

[0167] Please refer to it again. Figure 14 The second guide rod 63b extends along the Z-axis. It is positioned within the second groove 617. The second guide rod 63b can be fixed within the fourth groove 6273 of the fixing base 62. It can slide relative to the second groove 6136. It is understood that the second guide rod 63b can also be fixed to the fixing base 62 by bonding or welding. In other embodiments, the second guide rod 63b can be integrally formed with the fixing base 62.

[0168] In other embodiments, the second groove 6136 may also be provided in the fixing base 62. The fourth groove 6273 may also be provided in the first plate 613. In this case, the second guide rod 63b may also be fixed in the fourth groove 6273 of the first plate 613. The first guide rod 63a slides relative to the second groove 6136 of the fixing base 62.

[0169] In this embodiment, the cooperation of the first guide rod 63a and the first slide groove 616, and the cooperation of the second guide rod 63b and the second slide groove 617, provides guidance during the sliding of the outer shell 61 relative to the fixed seat 62. This makes the sliding direction of the outer shell 61 relative to the fixed seat 62 more accurate, and the outer shell 61 is less prone to deviation. Furthermore, compared to the solution that uses the deformation of a spring to move the fixed seat 62, this embodiment, through the cooperation of the first guide rod 63a and the first slide groove 616, and the cooperation of the second guide rod 63b and the second slide groove 617, is not limited by the first guide rod 63a and the second guide rod 63b, allowing the outer shell 61 to slide a longer distance relative to the fixed seat 62. For example, the maximum distance the outer shell 61 can slide relative to the fixed seat 62 along the Z-axis can be 5 mm. In this case, the distance the outer shell 61 can slide relative to the fixed seat 62 along the Z-axis is within the range of 0 to 5 mm.

[0170] Combination Figure 13 As shown, the arc surface of the protrusion 6143 of the second plate 614 cooperates with the clearance groove 6275 of the fixed seat 62, which can play a further guiding role during the sliding of the outer shell 61 relative to the fixed seat 62. In this way, the outer shell 61 is more stable during the sliding process relative to the fixed seat 62, that is, the outer shell 61 is not easy to tilt.

[0171] Please see Figure 15 , Figure 15 yes Figure 5 The image shows a partial cross-sectional view of the lens motor 60 along line EE. A first magnetic member 66 is fixed within a first fixing groove 6137 of the first plate 613. A second magnetic member 67 is fixed within a second fixing groove 6274 of the fixing base 62. The first magnetic member 66 and the second magnetic member 67 can attract each other. In this embodiment, the first magnetic member 66 and the second magnetic member 67 can generate an attractive force in the Y-axis direction. Thus, the first plate 613, the first guide rod 63a, the second guide rod 63b, and the fixing base 62 can remain in contact under the action of the attractive force, making it less likely for the fixing base 62 to wobble relative to the first plate 613. Figure 14As shown, since the groove wall of the first groove 6135 is "V" shaped, when the first magnetic member 66 and the second magnetic member 67 generate an attraction in the Y-axis direction, the two groove walls of the first groove 6135 can apply a force to the first guide rod 63a, thus clamping the first guide rod 63a between the two groove walls of the first groove 6135. The connection between the first plate 613, the first guide rod 63a, and the fixing seat 62 is more stable. In addition, by setting the second groove 6136 of the first plate 613 to be "[", circular, or U-shaped, a certain error can be reserved between the groove wall of the second groove 6136 and the second guide rod 63b in the X-axis direction, so that the second guide rod 63b and the second groove 6136 will not be difficult to assemble due to positional errors.

[0172] Please refer to it again. Figure 15 In this embodiment, there are two first magnetic attractors 66 and two second magnetic attractors 67. The two first magnetic attractors 66 are fixed one-to-one in the two first fixing slots 6137. The two second magnetic attractors 67 are fixed one-to-one in the two second fixing slots 6274. This results in a greater force between the first plate 613 and the fixing base 62 in the Y-axis direction, and a more stable connection between the first plate 613, the first guide rod 63a, the second guide rod 63b, and the fixing base 62. In other embodiments, the number of first magnetic attractors 66 and second magnetic attractors 67 is not specifically limited.

[0173] In one embodiment, both the first magnetic attractor 66 and the second magnetic attractor 67 can be magnets.

[0174] In one embodiment, one of the first magnetic attractor 66 and the second magnetic attractor 67 is a magnet, and the other is a magnetic conductor.

[0175] In this embodiment, the two second magnetic attractors 67 are located between the first guide rod 63a and the second guide rod 63b. In this way, the attraction between the two first magnetic attractors 66 and the two second magnetic attractors 67 is more concentrated, which helps to improve the connection stability between the first plate 613, the first guide rod 63a, the second guide rod 63b and the fixing base 62.

[0176] In other embodiments, the second magnetic member 67 is located on the side of the first guide rod 63a away from the second guide rod 63b.

[0177] In other embodiments, the second magnetic member 67 is located on the side of the second guide rod 63b away from the first guide rod 63a.

[0178] In other embodiments, the number of second magnetic members 67 is two. One second magnetic member 67 is located on the side of the first guide rod 63a away from the second guide rod 63b. The other second magnetic member 67 is located on the side of the second guide rod 63b away from the first guide rod 63a.

[0179] Please see Figure 16 , Figure 16 yes Figure 5 The image shows a partial cross-sectional view of the lens motor 60 at the FF line. Both the first magnet 65a and the second magnet 65b are fixedly connected to the housing 61. Exemplarily, the first magnet 65a is fixed to the third side plate 6124 of the frame 612. The second magnet 65b is fixed to the fourth side plate 6125 of the frame 612.

[0180] In one embodiment, the first magnet 65a can be first fixed to a first magnetic conductor (not shown), and then the first magnetic conductor can be fixed to the third side plate 6124 of the frame 612. The first magnetic conductor is used to enhance the magnetism of the first magnet 65a. Exemplarily, the first magnetic conductor can be in the shape of a "frame".

[0181] In one embodiment, the second magnet 65b may be first fixed to the second magnetic conductor. Then, the second magnetic conductor is fixed to the fourth side plate 6125 of the frame 612. The second magnetic conductor is used to enhance the magnetism of the second magnet 65b. Exemplarily, the second magnetic conductor may be frame-shaped.

[0182] Please refer to it again. Figure 16 The first coil 64a and the second coil 64b are both fixedly connected to the mounting base 62. Exemplarily, the first coil 64a can be fixedly connected to the third side 625 of the mounting base 62 and disposed opposite to the first magnet 65a. The second coil 64b can be fixedly connected to the fourth side 626 of the mounting base 62 and disposed opposite to the second magnet 65b. It is understood that when a signal is applied to the first coil 64a and the second coil 64b, the first magnet 65a can engage with the first coil 64a, and the second magnet 65b can engage with the second coil 64b, thereby pushing the housing 61 relative to the mounting base 62 and causing it to slide along the X-axis.

[0183] In other embodiments, the fixed positions of the first magnet 65a and the first coil 64a can be interchanged. The fixed positions of the second magnet 65b and the second coil 64b can also be interchanged.

[0184] Please refer to it again. Figure 16 In this embodiment, by fixing a first magnet 65a and a second magnet 65b to the outer casing 61, and fixing a first coil 64a and a second coil 64b to the fixing base 62, the Lorentz force generated by the first magnet 65a and the first coil 64a, and the Lorentz force generated by the second magnet 65b and the second coil 64b, are used to drive the outer casing 61 to slide relative to the fixing base 62 along the Z-axis direction. Furthermore, in conjunction with... Figure 14As shown, by setting the cooperation of the first guide rod 63a and the first slide groove 616, and the cooperation of the second guide rod 63b and the second slide groove 617, a guiding function can be played during the sliding of the outer shell 61 relative to the fixed seat 62, thereby making the outer shell 61 slide more accurately along the Z-axis direction, that is, the outer shell 61 is not easy to deviate. In addition, combined with Figure 15 As shown, by fixing the first magnetic member 66 in the first fixing groove 6137 of the first plate 613 and the second magnetic member 67 in the second fixing groove 6274 of the fixing base 62, the attraction force generated by the first magnetic member 66 and the second magnetic member 67 in the Y-axis direction is used to tightly connect the first plate 613, the first guide rod 63a, the second guide rod 63b and the fixing base 62. In this way, the fixing base 62 is less likely to wobble relative to the first plate 613.

[0185] Please see Figure 17 , Figure 17 yes Figure 4 The image shows a partial cross-sectional view of the lens assembly 60a at line GG. In one embodiment, the first lens 71 includes a lens cap 711, a first lens barrel 712, and first lens elements 713. The number of first lens elements 713 can be one or more. When there are multiple first lens elements 713, they can be arranged sequentially along the Z-axis. Exemplarily, at least one first lens element 713 is fixed between the lens cap 711 and the first lens barrel 712. The remaining first lens elements 713 are fixedly connected to the first lens barrel 712.

[0186] In this embodiment, there are three first lens elements 713. The first lens elements 713 are fixedly connected to the first lens barrel 712. The lens cover plate 711 is fixedly connected to the first lens barrel 712. Exemplarily, the first element of the first lens element 713 is fixed between the lens cover plate 711 and the first lens barrel 712; that is, the first element of the first lens element 713 is also fixedly connected to the lens cover plate 711. The remaining elements of the first lens element 713 are fixed inside the first lens barrel 712. In other embodiments, the fixed position of the first lens elements 713 is not limited.

[0187] In one embodiment, the second lens 72 includes a second lens barrel 721 and a second lens element 722. The number of second lens elements 722 can be one or more. When there are multiple second lens elements 722, they can be arranged sequentially along the Z-axis. In this embodiment, there are three second lens elements 722. The second lens elements 722 are fixedly connected to the second lens barrel 721.

[0188] In one embodiment, a first lens 71 is fixedly connected to a mounting base 62. At least a portion of the first lens 71 is located within a mounting hole 6271 in the mounting base 62. Exemplarily, the first lens barrel 712 of the first lens 71 can be fixedly connected to the wall of the mounting hole 6271 by means of adhesive bonding or the like.

[0189] In one embodiment, the second lens 72 is fixed to the base plate 611 of the housing 61. The image side of the second lens 72 is disposed opposite to the light-transmitting hole 6111 of the base plate 611. The second lens 72 is located on the image side of the first lens 71.

[0190] Please refer to it again. Figure 17 , Figure 17 This is a schematic diagram of the lens assembly 60a when the electronic device 1 is in the pop-up state. Thus, when the electronic device 1 is in the pop-up state, at least a portion of the second lens 72 can be located within the fixing hole 6271 of the fixing base 62. At this time, the second lens 72 is positioned close to the first lens 72.

[0191] Please see Figure 18 , Figure 18 yes Figure 2 The diagram shows a partial cross-sectional view of the electronic device 1 in a focused state. A first lens 71 is fixedly connected to a camera trim 80. Exemplarily, the lens cover 711 of the first lens 71 is fixedly connected to the camera trim 80 by means of adhesive bonding or the like.

[0192] When the electronic device 1 is in the focusing state, a small portion of the second lens 72 can be located within the fixing hole 6271 of the mounting base 62. At this time, the second lens 72 is positioned away from the first lens 71. In other words, when the electronic device 1 is in the focusing state, the distance between the first lens 71 and the second lens 72 is greater than the distance between the first lens 71 and the second lens 72 when the electronic device 1 is in the pop-up state.

[0193] Understandably, when the electronic device 1 transitions from the pop-up state to the focusing state, the housing 61 slides along the negative Z-axis under the drive of the first magnet 65a and the first coil 64a, and the second magnet 65b and the second coil 64b. At this time, the housing 61 can move the first magnet 65a, the second magnet 65b, and the second lens 72 along the negative Z-axis. The distance between the second lens 72 and the first lens 71 increases, and the distance between the second lens 72 and the photosensitive chip 20 decreases. When the electronic device 1 transitions from the focusing state to the pop-up state, the housing 61 slides along the positive Z-axis under the drive of the first magnet 65a and the first coil 64a, and the second magnet 65b and the second coil 64b. At this time, the housing 61 can move the first magnet 65a, the second magnet 65b, and the second lens 72 along the positive Z-axis. The distance between the second lens 72 and the first lens 71 decreases, and the distance between the second lens 72 and the photosensitive chip 20 increases.

[0194] It is understandable that when electronic device 1 is in the pop-up state, if camera module 100 can take pictures normally, camera module 100 does not need to focus. At this time, the pop-up state of electronic device 1 can also be the focusing state of electronic device 1.

[0195] In this embodiment, since the maximum sliding distance of the housing 61 relative to the fixing base 62 along the Z-axis can be 5 mm, the maximum focusing distance of the camera module 100 can be 5 mm. In other words, the focusing travel of the camera module 100 is within the range of 0 to 5 mm. The structure of one embodiment of the lens assembly 60a has been described in detail above with reference to the accompanying drawings. Other configurations of the lens assembly 60a will be described in detail below with reference to the accompanying drawings.

[0196] First, with reference to the relevant accompanying drawings, we will introduce in detail a method for electrically connecting the first coil 64a and the second coil 64b to external devices.

[0197] Please see Figure 19 , Figure 19 yes Figure 6 The diagram shows the structure of the motor circuit board 68 from another angle. The motor circuit board 68 includes a first part 681, a second part 682, a third part 683, and a fourth part 684. The second part 682 connects between the first part 681 and the third part 683. The first part 681 and the third part 683 are positioned opposite each other. The fourth part connects to the second part.

[0198] Please see Figure 20 , Figure 20 yes Figure 6The diagram shows the assembly of the motor circuit board 68, the mounting base 62, and the base plate 611. The motor circuit board 68 is fixedly connected to the mounting base 62. Exemplarily, the first portion 681 of the motor circuit board 68 is fixedly connected to the third side 625 of the mounting base 62. The third portion 683 of the motor circuit board 68 is fixedly connected to the fourth side 626 of the mounting base 62. The second portion 682 of the motor circuit board 68 is fixedly connected to the second side 624 of the mounting base 62.

[0199] Please see Figure 20 and combined Figure 12 As shown, the fourth portion 684 of the motor circuit board 68 can pass through the second plate 614 and the second side plate 6123 of the housing 61, extending to the outside of the housing 61. The fourth portion 684 of the motor circuit board 68 can be used with the module circuit board 10 (see [link to module circuit board 10]). Figure 18 Electrical connection. In this way, electrical signals can be transmitted between the module circuit board 10 and the motor circuit board 68.

[0200] Please refer to it again. Figure 20 The first coil 64a is fixed to the first portion 681 of the motor circuit board 68 and is electrically connected to the motor circuit board 68. Thus, the first coil 64a, the motor circuit board 68, and the module circuit board 10 (see [reference]) are connected. Figure 18 It can form a current loop.

[0201] The second coil 64b is fixed to the third portion 683 of the motor circuit board 68 and is electrically connected to the motor circuit board 68. Thus, the second coil 64b, the motor circuit board 68, and the module circuit board 10 (see [reference]) are connected. Figure 18 It can form a current loop.

[0202] In other embodiments, the lens motor 60 may not include a motor circuit board 68. The first coil 64a can be electrically connected to the module circuit board 10 via wires. The second coil 64b can be electrically connected to the module circuit board 10 via wires.

[0203] The following section will describe a closed-loop configuration of the lens assembly 60a in detail with reference to the accompanying drawings.

[0204] Please see Figure 21 and combined Figure 20 As shown, Figure 21 yes Figure 5The lens assembly 60a shown is a partial cross-sectional view of another embodiment. The lens motor 60 may also include a tunnel magnetoresistive (TMR) sensor 73 and a magnetic grating 74. The TMR sensor 73 may be fixed to and electrically connected to the motor circuit board 68. The magnetic grating 74 may be fixed to the housing 61. The TMR sensor 73 may be disposed opposite to the magnetic grating 74. Exemplarily, the TMR sensor 73 may be fixed to a second portion 682 of the motor circuit board 68. The magnetic grating 74 may be fixed to a second plate 614 of the housing 61. In other embodiments, the positions of the TMR sensor 73 and the magnetic grating 74 may be interchanged.

[0205] In this embodiment, the tunnel magnetoresistive sensor 73 is used to detect the magnetic field strength of the magnetic grating 74 at different positions. When the housing 61 moves relative to the fixed base 62 along the Z-axis, the housing 61 can drive the magnetic grating 74 to move relative to the fixed base 62 along the Z-axis. The tunnel magnetoresistive sensor 73 can detect the magnetic field strength at the location of the magnetic grating 74. Thus, when the tunnel magnetoresistive sensor 73 detects the magnetic field strength of the magnetic grating 74, the displacement of the housing 61 can be determined by the magnetic field strength. It can be understood that through the cooperation of the tunnel magnetoresistive sensor 73 and the magnetic grating 74, the displacement of the housing 61 relative to the fixed base 62 along the Z-axis can be accurately controlled, thereby realizing the closed-loop design of the lens assembly 60a.

[0206] In addition, compared to the solution using a Hall sensor and a magnet, this embodiment uses a combination of a tunnel magnetoresistive sensor 73 and a magnetic grating 74, which can accurately measure the outer shell 61 with large displacement.

[0207] In one embodiment, lens assembly 60a may include a driver chip (also referred to as a driver IC). The driver IC is electrically connected to a first coil 64a and a second coil 64b. The driver chip can transmit current to the first coil 64a and the second coil 64b. The driver chip may be located within the area enclosed by the first coil 64a or within the area enclosed by the second coil 64b.

[0208] In one embodiment, the tunnel magnetoresistive sensor 73 can be integrated into an IC chip. In this case, the IC chip has the function of the tunnel magnetoresistive sensor 73, that is, the IC chip can be used to detect the magnetic field strength of the magnetic grating 74 at different locations.

[0209] Please see Figure 22 , Figure 22 yes Figure 4The image shows a partial cross-sectional view of the lens assembly 60a in another embodiment. In one embodiment, the mounting base 62 is provided with a first buffer 75. The first buffer 75 is fixedly connected to the bottom surface 622 of the mounting base 62. Thus, when the camera module 100 moves from the focusing state to the pop-out state, the housing 61 can drive the first magnet 65a, the second magnet 65b, and the second lens 72 to move in the positive direction of the Z-axis. At this time, the first buffer 75 can buffer the collision force between the bottom plate 611 of the housing 61 and the mounting base 62 to prevent damage to the bottom plate 611 of the housing 61 or the mounting base 62. In other embodiments, the first buffer 75 may also be fixedly connected to the top surface of the bottom plate 611 of the housing 61.

[0210] For example, the first buffer 75 can be rubber, a spring, a sheet, silicone, or other elastic components. In this embodiment, the first buffer 75 is rubber.

[0211] Please see Figure 23 , Figure 23 yes Figure 2 The diagram shows a partial cross-sectional view of the camera module 100 in another embodiment. In one embodiment, the camera module 100 includes a second buffer 76. The second buffer 76 is fixedly connected to the bottom surface 622 of the base plate 611 of the housing 61. Thus, when the camera module 100 transitions from an ejected state to a non-ejected state, the camera trim 80 can drive the lens assembly 60a to move along the negative Z-axis. At this time, the second buffer 76 can buffer the collision force between the base plate 611 of the housing 61 and the base 50 to prevent damage to the base plate 611 or the base 50.

[0212] For example, the second buffer 76 may be made of rubber, spring, sheet metal, silicone or other elastic components.

[0213] The preceding text, with reference to the accompanying drawings, provides a detailed description of an embodiment of an electronic device 1. The following text, with reference to the accompanying drawings, will further describe the structure of another electronic device 1. Technical details identical to those in the preceding embodiment will not be repeated.

[0214] Please see Figures 24 to 26 , Figure 24 This is a cross-sectional view of an electronic device 1 provided in another embodiment of this application. Figure 25 yes Figure 24 The cross-sectional view of the electronic device 1 in the pop-up state is shown. Figure 26 yes Figure 24The diagram shows a cross-sectional view of the electronic device 1 in its focused state. In this embodiment, the first lens 71 of the lens assembly 60a is separately disposed from the camera trim 80. In other words, the first lens 71 of the lens assembly 60a is no longer fixedly connected to the camera trim 80. The electronic device 1 of this embodiment also has three states, and the camera module 100 also has three corresponding states. In other words, the camera module 100 has a non-pop-up state, a pop-up state, and a focused state.

[0215] Please refer to it again. Figure 24 When the electronic device 1 is in the non-pop-up state (i.e., the camera module 100 is in the non-pop-up state), the distance between the camera module 100 and the camera decorative piece 80 in the Z-axis direction is the first distance. Please refer again. Figure 25 When the electronic device 1 is in the pop-up state (i.e., the camera module 100 is in the pop-up state), the distance between the camera module 100 and the camera decorative piece 80 in the Z-axis direction is the second distance. The second distance is greater than the first distance. It can be understood that this embodiment, by adding an extra state of the camera module 100 (i.e., the pop-up state of the camera module 100), allows the camera module 100 to have a larger focusing range in the Z-axis direction during operation. This will be described in detail below with reference to the accompanying drawings.

[0216] Please refer to it again. Figure 24 and Figure 25 When the electronic device 1 transitions from a non-pop-up state to a pop-up state, the drive device 90 drives the camera decorative piece 80 to move relative to the back cover 202 along the positive Z-axis, allowing at least a portion of the camera decorative piece 80 to move outside the mounting hole 203. At this time, the distance between the camera decorative piece 80 and the camera module 100 increases. When the electronic device 1 transitions from a pop-up state to a non-pop-up state, the drive device 90 drives the camera decorative piece 80 to move relative to the back cover 202 along the negative Z-axis, allowing at least a portion of the camera decorative piece 80 to move inside the mounting hole 203. At this time, the distance between the camera decorative piece 80 and the camera module 100 decreases.

[0217] Please refer to it again. Figure 26 When the electronic device 1 is in focusing mode, the second lens 72 is positioned away from the first lens 71. In other words, when the electronic device 1 is in focusing mode, the distance between the first lens 71 and the second lens 72 is greater than the distance between the first lens 71 and the second lens 72 when the electronic device 1 is in pop-up mode.

[0218] It is understandable that when electronic device 1 is in the pop-up state, if camera module 100 can take pictures normally, camera module 100 does not need to focus. At this time, the pop-up state of electronic device 1 can also be the focusing state of electronic device 1.

[0219] Understandably, when the electronic device 1 transitions from the pop-up state to the focusing state, the mounting base 62 slides along the positive Z-axis under the drive of the first magnet 65a and the first coil 64a, and the second magnet 65b and the second coil 64b. At this time, the mounting base 62 can drive the first coil 64a, the second coil 64b, and the first lens 71 to move along the positive Z-axis. The distance between the first lens 71 and the second lens 72 increases, and the first lens 71 moves away from the photosensitive chip 20. When the electronic device 1 transitions from the focusing state to the pop-up state, the mounting base 62 slides along the negative Z-axis under the drive of the first magnet 65a and the first coil 64a, and the second magnet 65b and the second coil 64b. At this time, the mounting base 62 can drive the first coil 64a, the second coil 64b, and the first lens 71 to move along the negative Z-axis. The distance between the first lens 71 and the second lens 72 decreases, and the first lens 71 moves closer to the photosensitive chip 20.

[0220] In this embodiment, the distance between the first lens 71 and the second lens 72 is increased or decreased by sliding the fixing base 62 relative to the outer casing 61, thereby achieving focusing of the camera module 100. The camera module 100 in this embodiment has a relatively large focusing distance. For example, the maximum focusing distance of the camera module 100 can be 5 mm. That is, the focusing distance of the camera module 100 is in the range of 0 to 5 mm.

[0221] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
